CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 418,238, dated December31, 1889. Application filed October 4,1889. Serial No. 325,978. (Nomodel.)

.To @ZZ 7,071,071?, t may concern.:

Be it known that I, DAMON D. SHAW, a citizen of the United States,residing at 'Bi g Bend, in the county of Phillips and State of Kansas,have invented a new and useful Car-Coupling', of which the following isa specification.

My invention relates to improvements in car-couplings; and it consistsin certain novel features, hereinafter described and claimed.

In the accompanying drawings, Figure l is a perspective view of myimproved car-coupling'. Fig. 2 is a plan View of the same, showing itarranged to permit the uncoupling of the cars. Fig. 3 is a detailperspective View showing-the inner end of one member of the draw-headand the support therefor.

In carrying out my invention I employ the beams A A, which are securedto the bottom of the car at the end of the same, and are provided withhorizontal longitudinal slot-s B B, in which the ends of the supports CC are inserted. Between the ends of the slots B and the front and rearsides of the supports C, I arrange the springs D D, the said springsallowing the supports C to yield to the blow put thereon when the' carscome to getherin the operation of coupling. The supports C C areprovided in their inner sides with the curved grooves E E, and thesegrooves are engaged by curved ribs F F on the members of the draw-head,so that the said members will be held in their proper places' at alltimes. The draw-head is composed of two members G G, which are pivotedto the supports C C, the pivot-pin passing downward between the ribs Fand the grooves E,

before referred to. The front ends of the members 'of the draw-head areprovided in th eirinner sides with thelongitudinal grooves I-I II, whichfit around the coupling-link, and the members are further provided withthe transverse openings I, which engage the arrow-heads of thecoupling-link and prevent withdrawal of the same, thereby coupling theparts together. The members of the drawhead are normally pressedtogether by the springs J, secured to one member and bearing on thefront end of the other member. On the upper side of one, member I pivot'to be locked thereto by a pin M.

an operating-lever K, which passes under a plate L on the other member,and is adapted The lever is further connect-ed with the opposite memberof the draw-head by a link N, as clearly shown.

The construction and arrangement of the parts being thus made known, theoperation of the device will be readily understood. When it is desiredto couple the two cars together, the coupling-link is secured in onedraw-head by hand, and the two cars then brought together. The link willthus be guided into the opposing draw-head, and the head of the samewill be engaged bylthe shoulders of the draw-head, thereby coupling thecars together. As the link enters the draw-head, its arrow-head willpush the members of the draw-head apart and clear the shoulders, afterwhich the springs throw the members of the draw-head together. Thelocking-pin is then inserted in place to secure the lever. Then it isdesired to uncouple the cars, the locking-pin is removed and the leveris then swung forward, so as to separate the members of the draw-headand permit the removal of the link. The drawhead may be arranged onpassenger-cars so that the lever will be vertical insteadof hori zontal,and the members of the draw-head are provided in their opposing sideswith recesses, which, when together, will support an ordinarycouplingpin, so that the ordinary pinand-link coupling may be used.

From the foregoing description it will be seen that I have provided acar-coupling which is very simple in its construction, and which willautomatically couple the cars. The device can move freely on itsconnection with the cars, so as to easily pass around curves, and theadvantages of the device are thought to be obvious.

I-Iaving thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-
